A brand new OTA began rolling out to the 2013 Nexus 7 LTE just two days ago, and today those changes finally appeared in AOSP. As is the tradition, Al Sutton built a list of changes and posted them to his site. Every bug fix and tweak from KOT49H (4.4.2_r1) to KVT49L (4.4.2_r2) is included. There isn't a lot to look at, but if you're interested in what's new, you can find the developer changelog here.

Android 4.4.1 source files haven't even rested in the repositories of the Android Open Source Project long enough to get cold, and they're already getting served up by a fresher helping of code. Google has made the Android 4.4.2 files available in AOSP under the release tag android-4.4.2_r1. The platform/build repo confirms that this is KOT49H.

This release came hot on the heels of the 4.4.1 release, so don't expect much in the way of changes.
